Looks like some sort of library conflict as the Kubernetes Client seems to be upgraded here compared to what quarkus provides with 1.12.0 version.

Any ideas how to resolve this?

@mswiderski - The code changes did by @metacosm. The above issue is resolved now. Please re-try again. I was also facing same problem.
